BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a golf club grip, more specifically, a golf club grip that is instilled with a publicity use of printing layer displaying the pictures or diagram, letters and so on inside of grip so that the intended publicity can be easily seen externally, and also prevents the damage of printing layer as well as the contents of publicity that is printed on the printing layer can be seen more clearly externally.

2. Background of the Related Art

In general, the grip of golf club has to be easy to use—that is, easy to grab and not slippery, thus the golf club manufacturers normally use a thin and long band or band shaped rubber or coverings made of synthesized resin to form a certain thickness of layer around the handle of shaft or plaster it with a synthesized resin that is glued to the end of shaft. However, this conventional method of making grip requires a lot of effort, time and money to form the shape, and in case of using the layering method, it is difficult to measure precisely how much covering is needed due to the difficulty of locating and distancing the material on the grip and there is often under/over stock of the material.

When playing golf, the player perspires a lot in his/her hands so grip is a part where it is easily contaminated and spoiled by the sweat thus, it is normal that the grip formed by the above coverings or plasters are transparent and manufactured in dark colors such as black or dark blue, etc.

The grip is the most noticeable part of golf club and it attracts the eyes of user the most thus, all the manufactures print their publicity letters or diagram such as the company logo or name of product and etc., on the top layer of grip of golf club, or mold it by the use of raising or engraving and color the molded part to highlight or, stick the printed advertisement on the exterior to show the origin of the advertisement or the publicity. Such grip of golf club is the most noticeable part of golf club and also the part where user has the most direct and frequent contacts.

However, this conventional type of prints where the printed contents of advertisement is on the surface of grip has a number of problems. It can easily be contaminated and spoiled by the sweat of user and dirt, also when the raising and engraving method is used, it is often difficult for the user to understand the contents of advertisement, and in case of using the sticker with the advertising contents, due to the sweat in hands of player, it comes off easily and the adhesive part of sticker sticks to the hands of user which make him/her feeling uncomfortable and irritated by having the sticky hands.

Above shape memory alloy (40) is used to make it easy to put on/take off to the shaft (S) of grip (G), if heat is added to the grip (G) during assembly, shape memory allow (40) is open to the exterior, i.e. the body of grip (10) is open to the exterior by the shape of allow (40) it is possible to insert body of grip (10) to the shaft (S), on the other hand, some time after the assembly when the temperature drops, the shape memory alloy is shrink to the original condition thus, it prevents the slipping of grip (G), and like this, the condition where the body of grip (10) is laid in the shape memory alloy (40), if the user grabs the grip (G), according to the palm and finger temperature, the shape memory alloy (40) forms to the shape of user's finger and remembers the shape of it, it further enhances fuzzy feeling of grip (G).

Therefore, according to the grip of golf club of the present invention, above transparent layer (30) transmits all the ray of lights so that the print layer (20) inserted inside can display the advertisement contents clearly, also the print layer (20) is secured firmly between the body of grip (10) and the transparent layer (30), it can keep its original position without changing the position or without being damaged by any shock during the play.

In addition, it is easy for golfers to have a golf elbow. The golf elbow is occurred when the golfer puts too much shock on the muscle and nerve of low part of elbow when they are in the position to swing so the said part feels pain. When playing golf, if the player hits a ball directly by stroke or hit the ground instead, it can damage the joint and nerve of elbow. This kind of injury can be quite fetal to the golfers as it requires a long time to heal and at the same time, it incurs a lot of expenses to cure. To prevent this from happening, the player has to choose the right golf club and fix the posture of swing so that it does not give unnecessary stress to the joint or muscle. When Golf elbow is difficult to cure and even it is cured, re-occurrence rate is more than 50%. Thus, it is ideal to use the golf club that is composed of a grip that absorbs the shock. Having the elastic function of transparent layer (30), when the user swings the club, it reduces the shock dramatically and thus, it prevents the chance of having a golf elbow.

That is, the transparent layer (30) of grip (G) in accordance with the present invention is lower in the degree of hardness of rubber and high in solidity and maximum friction counts. If this is the case, when the user grabs the golf club, it gives the user an extra comfort. If the grab feeling is good it does not occur the twist when the user impacts on the ball thus it enhances the sense of direction of player. Also, the transparent layer (30) of the present invention which has a lower degree of hardness of rubber and high degree in solidity plays a role that reduces dramatically when the user swings the club.

The above explanation is only showing a few examples of practical use and the extent to the use of present invention is not limited to this, but it can apply to the variety of types and applications.
